LOCK.

SPECIFICATION forming part of Letters Patent No. 709,056, dated September 16, 1902.

Application iiled November 26, 1901l Serial No. 83.704- tNc models .T0 o/,ZZ whom, it may concern:

Be itknown that I, GEORGE GREGORY SMITH, a citizen of the United States, residingin Villa Bel Riposo, San Domenico, Florence, Italy, have invented certain new and useful Improvements in Locks, ot' which the following is a specification.

This invention relates to locks or bolts, and has for its object to provide an improved and eiiicient. lock for use upon doors,windows, duc.

Another object of the invention is to provide a lock which may be secured upon the outside of the place which it is desired to lock and in which the locking of the bolt will also control the means used to secure the lock in place.

In carrying out my invention I employ a bolt which is so constructed that it may be mounted upon a pin, one portion of which pin will be made to afford a pivot for the bolt and another portion of the pin will be made of some shape other than round, to which shape the pivotal part of the bolt will conform, so that the bolt when resting upon the part of the pin which is dissimilar in form to the pivot or the pivotless portion it will remain in whatever position it is placed upon such portion of the pin and when moved upon the pivot portion will be free to turn. To enable the lock to be applied to the outside of doors and similar positions where it is impracticable to secure the same in place by securing means which are exposed to the outside, I provide a plate which will overlie a portion of the screws and which will have some securing means which will be overlaid by the bolt when in its looked position. The screw-locking plate may be made to slide in ways in the frame of the lock and to be substantially dat upon the baseplate ot the lock. If dat-head screws are employed, the screwholes may be properly countersunk. If it is desired to use other forms of screws, the position for the plate will be so positioned that it will pass over the heads of the screws or nails or whatever fastening means is employed. If flat-head screws are used, the plate will be countersunk, and if a thin plate is employed part of the countersinking may be in such plate and part of it in the base-plate of the lock, such construction permitting the same kind of screws to be used for fastening the lock upon the structure with which it is i to be used and fastening the locking-plate. The screw for holding the screw-locking plate in'position might enter the base-plaie and not pass through into the structure to which the lock is applied. Such structure, however, would require the use of two different kinds of screws.

The lock may readily be used fora sash-fastener, in which organization instead of lockA ing the bolt in place a suitable spring-catch after the analogy of those used upon umbrellas may be applied upon a portion of the `pin for holding the bolt upon the pivotless portion.

In the drawings accompanyingand forming a part of the specification, Figure 1 is a front elevation ot' a forni of my improved bolt applied to a door. Fig. 2 isa top View thereof. Fig. 3 is a central vertical section on the line d a, Fig. 1. Fig. 1I is a form of pivot detached. Fig. 5 shows a framework for the lock. Fig. 6 is a detached plate.

The abutting edges of the structure which it is desired to Vsecure by a lock are designated in a general way A` B, respectively, to one of which, A, is attached myimproved lock,

`shown as comprising a framework 7, constituting a base-plate 8 and end portions 9 10, respectively. The base-plate is showin as provided with countersunk screw-holes 11, one of which holes 1 2 is shown as being countersunk a less distance than the others. Through the screw-holes suitable screws or nails 13 may be driven into the structure which it is desired to apply the lock to. The end members 9 and 10 are undercut on the inner side, forming Ways 14 15, to receive a plate 16, which is capable of sliding in the ways and covering the heads of all the screws 13 but one, and which plate is provided with a countersunk opening 17, capable of registry with one of the screw-holes 12 and which may, if desired, in conjunction with the countersink of the screw-hole 12, form a seat for the head of a screw similar to the serewsused in the other screw-holes, the organization being such that the plate will slide in the undercut ways after all the screws but one have been placed in position; and after the plate has been inserted and the screw passed through its screwhole and the screw-hole in the plate such IOO screw will control orwitli the other screws in place.

The end portions 9 and 10 are `shown pro vided with squared openings 18 and 19, respectively, through which a suitable pin 20, having correspondingly-squared ends 21 and 22 and a round pivot portion 23,'may be inserted, one of the squared ends 22 occupying substantially half of the portion of the pin between the ends 9 and 10. Upon the pin is mounted a suitablev bolt 24, having a squared opening correspondingtothe squared port-ion 22 of the pin. The pin may have a head 25 at one end and be upset or riveted at the other end to secure it in the framework. The round portion 23 of the pin forms a pivot for the bolt, the side of the squared ends being equal to the diameter of the pivot. The squared portion forms means for securely holding the bolt either in a locked or open position. It it is desired to unbolt the door when the device is in the position shown in Fig. 1, it issimply necessary to raise the bolt andswing it to one side, when it may be permitted to fall down upon the squared portion and there remain. A suitable lock may be provided, a keyhole 26 being shown, for locking the bolt upon the squared portion. If it is desired to use the bolt upon windoW-sashes, the pin may be provided with a suitable springcatch 27, entered by a bent end 28 in a hole 29 in the pivot and lyingin a groove 30, which spring and groove extend into the squared plate loc'kthe portion of the pin and into the squared portion of the'bolt. An upturued end 31 of the spring engages a depression 32 in such bolt. The spring is effective to hold the bolt upon the portion of the piny which locks it in such a manner that no instrument inserted from the outside can release the catch and slide the bolt od of its seat; but when it is desired to operate the bolt from the inside it is simply necessary to press down the catch with the finger and slide the bolt. The detent-spriug is also eifective to hold the bolt upon the pivot portion, and, if the device is used in connection with window-sashes, to hold the bolt upraised after it has been so raised to permit the opening of the Window. The screw which enters the plate will lie under the bolt when in its locked position. By this means the plate will cover all the screws but one, and the bolt will lock that screw against removal. Thus when the bolt is locked into position all of the screws will be locked against removal. This feature is important for permitting the lock to be used in positions where it is impracticable to secure the screws or bolts upon the inside and where it is desirable to use the lock upon the outside.

Although the device is shown with a round pivot and a square retaining portion, yet it will be obvious that any shapes on which the bolt may turn and` be held in place may be employed, and although the screws are shown as entered in countersinks and the securingplate substantially flat ou the base-plate of which will suggest themselves to the workman as the exigencies of manufacture may require. L
